Specification of Letters Patent.

Patented March 19, 1907.

Application filed December 3, 1906. Serial No.l 346,137.

To all whom it may concern:

Be it known that LAMos MORTON BARKER, a citizen of the United States, and a resident of Franklin, in the county of Franklin and State of Nebraska, have invented a new and Improved Cultivator, of which the following is a full, clear, and exact description.

This invention relates to straddle-row cultivators, and has for its object to provide means simple in construction, eective in operation, and durable in use adapted to cultivate one or more rows of plants, as may be desired.

Other objects relating to the specific construction and special arrangement of the several parts of my invention will be understood from the following description and accompanying drawings, in which drawings like characters of reference indicate like parts throughout the views, and in which- Figure 1 is a plan of a cultivator embodying my invention. Fig. 2 is a side elevation of the same, taken on the line 2 2 of Fig. 3. Fig. 3 is a rear elevation of a carrying-frame and connecting mechanism, taken on the line 3 3 of Fig. 2. Fig. 4 is a perspective view of a shoe upon which the main frame of the cultivator is mounted. Fig. 5 is a transverse section of cultivator-beams and means for raising the same shown in front elevation, and Fig. 6 is a side elevation of means for adjustably connecting together plow-beams, which are shown in cross-section.

As illustrated in the drawings, the main frame of the cultivator comprises a carryingframe having uprights 1, connected at their up er ends byv means of a cross-bar 2 and attac ed at their lower ends to sleeves 3, fixedly secured to shoes 4, which are thereby adapted to support the main frame and the gangbeams mounted thereon. The gang-beams V5 are secured in the ordinary manner to the offset ends 6 of an arched gang-frame comprising upright bars 7, connected together at their up er ends by means of a cross-bar 8. An auxi iary frame is connected with the main frame by means of a bar 9, referablyv attached to the main gang-frame y means of a bolt 10. The connecting-bar 9 is l rovided with a vertical standard 11, forme integral therewith, having an oset arm 12, forming an auxiliary gang-frame. The auxiliary gang-frame is mounted upon an auxiliary frame consisting of the vertical standard 13, having an offset upper end 14, connected with the standard 11 of the auxiliary gang-frame, and is supported at its lower end by a shoe 4, having a` sleeve 3 fixedly attached thereto. The main and auxiliary gang-frames are adjustable upon the main and auxiliary carrying-frames by means of sleeves 15, which are secured to the gangframe in any suitable manner and have a sliding engagement with the vertical standards 1 and 18 of the main carrying-frame and auxiliary carrying-frame, respectively, and are secured on said standards at the proper adjustment by means of set-screws 16 or other suitable means. By means of such vertical adjustment of the gang-frames the gang-beams and the plows mounted thereon are adjusted at the desired elevation.

A sulky-frame is connected with the gangframes in any suitable manner and may be of any desired construction, but consists, preferably, of side bars 17, looped together at their rear ends and connected at their forward ends to the gang-beams, as shown in Fig. 3. A transverse bar 18 is journaled in bearings 19, which are secured to the side bars 17 of the sulky-frame, and said bar is provided with forwardly-projecting arms 20, having chains 2l connected therewith at their upper ends and at their lower ends with the gang-beams 5, whereby the gang-beams may be raised from the ground or held at the desired elevation by rotating the transverse shaft 18. A lever 22 is connected with said shaft and is adapted to engage a notched standard 23, so as to hold the gang-beams at the desired elevation when adjusted. The rear end of the sulky-frame is supported upon a carrying-wheel 24, having its axle 25 mounted upon a yoke 26, which is provided with a pivotal attachment to`a bracket 27, connected with the sulky-frame by means of arms 28, diverging from said standard 27, and connected at their upper ends with thev side bars 17 of the sulky-frame. A seat-support is attached to the rock-shaft 18, and consists, preferably, of parallel bars' 29, adapted to enable a seat 30 to be mounted and slide thereon. The forward ends of the bars 29 preferably diverge from each other roc and connect with the rock-shaft 18, so as to make a strong connection with said shaft. Foot-rests 3l are attached to the side bars 17 of the sulky-frame and are arran-ged in convenient relation with the seat 30. A tongue 32 is secured to the beam-frame in any suitable manner and is supported on said frame by means of a bracket formed of bars 33, adapted to support said tongue at their upper ends and connected at their lower ends to the upright bars '7 of the mainframe. Swingletrees 34 areV connected with the mainand auxiliary carrying-frame in any sui-table manner, preferably by means of brackets, having upper arms 35 connected with the uprights of said carrying-frame, and vertical bars 36, secured at their lower ends to the shoes 4. Auxiliary shoes 37 may be used, if desired, and made considerably wider than the shoes 4, so as to furnish a broader bearing for the main frame. Vhen such construetion is used, I prefer to-formthe shoe with an offset rear central portion ,38, formed by making a transverse slit 39 i-n the rear portion of the shoe, so as to form a socket adapted to` receive the rear end of the shoe 4 and hold said end securely in place. The for- Ward ends of the shoes 37 are connected with the forward ends of the shoes 4 and the bars 36 by means of bolts 40, which enable the auxiliary shoes tobe readily applied' to the main shoes 4 or removed therefrom when desired.

The gang-beams 5 are connected together by means of interlocking cross-bars 41, having offset ends 42, provided with eyes adapted to receive the shank of the opposite bar, and are secured in place by means of setscrews 43, thereby enabling the gang-beams to be adjusted at the desired distance apart.

Having thus described my invention., what I claim as new, andl desire to secure by Letters Patent, isn
